Phalera bucephala – Around 2:30 this morning I discovered this large moth resting on my shed. It is a master of disguise, for it can look like a broken Silver Birch twig. When at rest it holds its wings almost vertically against its body. Wingspan 42 to 55mm. The adult flies June and July, and is mainly seen in mixed woodland. Common and widespread. The larvae feed on various broadleaved trees including birches and sallows.
